Application iiled February 27, 1905, Serial No.` 247,588. Renewed September 11, 1908. Serial No. 452,662.

To all whom t may concern:

Be it known that l, FRAN oIs Kirn., arcitizen of the United States of America, and a resident of New York, iii the county of New York and State of New York, certify that l have invented a certain newanduseful Latch, of which the following Vis a-speciication, the same being a full, clear, and exact description of the invention, such as-will enable others skilled in the art to which it appertains to make and use the saine.

This invention relates to appliances designed for purposes of fastening movable articles, as swinging doors and the like, and in particular to latches 'for fastening and unfastening the doors of. refrigerators, ice boxes and other structures where air-tight doors are required, and it has for its object to provide a latch simple vand inexpensive in construction, readily applied and operated, and also eflicient in practical use.

1With this object in view the invention consists in certain novel features of construction and combination and arrangement of parts, all of which will be hereinafterV described and specifically pointed out in the drawings which accompany and form a part of this specification,` and in which- Figure l represents Y. an elevation of a door equipped with this invention; Fig. 2

a plan view of the same; Fig. 3 represents a plan view of the latching device proper; Fig. t is a front elevation thereof;

Fig. 5 is a plan view and Fig; 6 a front ele'- vation of the upper member of. the latch; Fig. T is a plan view and Fig. 8 a front elevation of the lower member of the latch; Fig. 9 are views in detail of the eccentric; and Figs. l0 and 11 are respectively a plan view and an. elevation of the auxiliary latch operated device.

. Like letters of reference indicate -like yparts in all the views.

Referring particularly to the drawings A, iii the present embodiment of theinvention, denotes a door, `and B the amb thereof. To the j amb B is ordinarily secured the keeper (.l-having a nosing Cl-and also one member or leaf D of a hinge, which may be of any suitable construction, the other member, strap or leaf D1 of which is attached to the door A. To the said door is also secured the latch consisting of, a casing E2, and upper member E, pivoted to the saine at e so as to work in a vertical direction, and al `ber E1, the said eccentric also being' contained within the casing E2 and in a recess `e3' of the upper member D; and the said rod projects or extends through the orifice c* of the casing E2 and is provided with a. controlling manually actuated device, as a handle FH The rod F may be used in con- Y nection witlivone or more of the latches constructed according to this inv-ention, three being shown in the present embodiment. ik rod H provided with a control `ling manually actuated device, as a handle HZ, serves as the pintle Yof the hinges D, D1.

VTo the door A is also fastened a plate J which serves to support a duplex lever mechanism consisting of two arms K, K1, connected` bya spindle 7c, the arm K working inv frontof the door and forming a socket for the lower end of the rod F, and the arm K1 working behind the door. Each of these arms is preferably constructed and arranged to jbe used as a treadle in order to raise the rod F. A spring .11 coiled around the spindle 7u serves to hold' the said two levers K, K1 in their normal horizontal positions, thereby retaining the rod F in its low or depressed position.

ln operation, when the dooi' A is closed, the preferably gravity latches E, El will fall in or behind the nosings C1 of the keepers C. In order now to force the outer edge of the door into the jainb, the handle F2 of the rod F is ordinarily pushed around to one side, as shown in Figs. l and 2, whereupon the eccentrics F1 will force the inner ends of the members El iii an inward direction, whereupon the said members will swing` on their pivots or joints c1 and the outer end of the said members will be pressed forward against the nosings C1,

`thereby forcing the outer edge of the door A backward into the jamb B. In order to open the door from the inside it is only necessary to press uponthe treadle formed by the pivoted am K1, whereupon the rod F will be raised and the latches lifted out of the keepers. The treadle formed by the pivoted arm K may also be used to raise the rod F, igt' desired, in order to render the operation of opening the door from the outside an easier one.

I do not claim in this application the specitic construction of the hinge herein shown and described, as the same is claimed in a divisional application Serial No. 290,825, tiled December 7th, 1905.

As it is evident that many changes in the construction, form, proportion and relative arrangement ol parts might be resorted to without depart-ing,` from the spirit and scope oit my invention, l would have it understood that I do not restrict myself to the particular construction and arrangement ot parts shown and described, but that such changes and equivalents may be substituted therefor, and that*n t hat l claim as my invention is:

l. In a latching device, a. latch consisting` et a plurality ot members, one being pivoted so as to move in a vertical direction, and the other being sustained by the irst member in a pivoted relation by a vertical joint so as to swingl in a horizontal directuate the said horizontally moving` member. Y Q. ,ln a latching device, a latch consisting` ot a plurality ot members, one being pivoted so as to move in a vertical direction,

latches, each consisting et a. plurality ot members pivoted so as to respectively move vertically and horizontally, and a common manually actuated device to control the latter, and means to cause the said latches to move vertically and also with an advance and retrograde movement as re- `rards said keepers.

4. YIii a. latchiiig` device, a keeper, in conibination with a latch consisting` ot a plurality ot members pivoted so as to respectively niove vertically and horizontally, and a manually actuated device to control the saine, and .means to cause the said latch to mov(` vertically and also with an advance and retrograde movement as regards the said keeper, and also in combination with auxiliary latch controlling means to cause the latch to move in a vertical direction.

5. ln a latcliiiitg device, a plurality ot keepers, in combination with a plurality ot latches, each consisting' ot a pluralityv ot members pivoted so as to respectively move vertically and horimintally, and a common manually actuated device to control thc latter, and means to cause the said tion, in combination with an eccentric to aclatches to move vertically and also with an advance and retrograde moven'ient as regards said keepers, and also in combination with auxiliary latch controlling means to cause the latches to move in a vertical direction.

ln testimony et the toregoing specification l do hereby sign the same in the city ot New York, county and State of New York, this 14th day ot February 1905.
